To all 107mm it may concern:

Be it known that l, WILLIAM Josnrn HAG- MAN, a citizen of the United States, residing at Philadelphia, Philadelphia county, Pennsylvania, have invented certain new and useful lm 'iroveinents in Planers for Locomotive- Cylinders, of which the following is a specification.

This invention, pertaining to improvements in plancrs designed particularly.for planing locomotive cylinders but available for other uses, will be readily understood from the following description taken in connection with the accompanying drawings in which F portions of an ordinary metal planer fitted with improvements exemplifying my present invention: Fig. 2 a plan of the same with some parts omitted: and 3 an end view of a locomotive cylinder illustrating the peculiar characterot the work designed to be accomplished by means 01 my improvements.

In the drawings Fig. 3 shows a form of locomol'ive cylinder in which the surfaces indicated, by 1 to 7 inclusive, are to be planed. It is to be noticed that in securing the casting tothe planer table in such manner as to leave suri'aces 6 and 7 'free to be reached by a planing tool, there is a very considerable overhang at portion 8 and if this overhanging portion is not support d, then di'tficulty would he found in planing the concave sur face found in the overhanging portion.

My improvements are designed to permit of the satisfz'tctory planing of all of the stated surfaces of such a cylinder as is illustrated in Fig, 3, at one setting of the cylinder.

Proceeding with the drawings 9, indicates the l ed of the planer: ll), the housings: 11, the tahle: 12, the rail: 13, the saddle of one ol the heads sliding on the rail: '14, a similar saddle on the rail: the saddle of the side-head sliding vertically on one of the housings: 16, the complete side-head sliding vertically on the other housing: 17, the vertical feed-screw l'orthe side-head 16: and 18, the handle shalt for turning the screw 17. All of the planer parts thus l ar referred to are or may he preciself as usual in ordinary planer practice and subject to any usual or suital'vle modifications in those parts, and the parts are adapted for working in their usual manner.

Proc eding with the drawings :---1. indiigure 1 is a front elevation of the maincates a saddle sliding on the rail: 20, a screw for adjusting this saddle along the rail: 21, a radius bar having its heel pivoted to saddle 19 and having its free end projecting inwardly in such manner that it may swing in the arc of a circle in a plane at right angles to the direction of motion otthe table: 22, a bar lying over the front face of the radius bar and having its ends secured to saddle 19 to serve in steadying the radius bar during its swinging motion: 23, a tool mounted in the free end of the radius bar: 24, a pivotbar mounted in the tool-clamps of side-head. 16 and carrying at its inner end a pivot with. its axis parallel with the direction of planing motion: 25, a link connectin pivot-bar 24 and the free end of the radius liar: 26, anarrow super-table secured to the planer table below tool 23: and 27, a longitudinal block secured to the top of the super-table.

The cylinder casting shown in Fig. 3 is to be secured with its base resting on the planer table and with its overhanging projection 8 resting on the block 27. Under these conditions the surfaces 1, 2, 3 and 4 can he operated upon by the usual tool-heads of the planer, say the rail-heads 13 and Hand the side-head 15. At the same time the overhang 8 of the casting is well supported for the operation of tool 23 which is to plane the concave surface 5'. The feeding motion for tool 23 can be derived from screw 17 feeding side-head 16 u )wardly or downwardly. The

ivot on whici the radius bar swings may e adjusted to a position corresponding Wlth the center of curve 5 by shifting saddle 19 on the rail. The length of the radius bar from the center of the pivot to the point of the tool, is to correspond with the radius of curve 5. It is to be noted that the radius bar has several selective pivot holes in its heeL-thus providing for quite a range of selective radii for the radius bar. Assuming the cylinder to be resting'en the planer table with its overhang 8 resting on top of block 27, it will be apprehended that surfaces 6 and 7 to beplaned are within a rather small space inelosed on all of its longitudinal sides, and that the tool to plane these two surfaces 6 and 7 must operate in this confined space.

Proceeding with the drawings 29, indicates a rail formed upon the inner-face of the super-tal'ile, parallel with the direction of planing motion: 30, a strut rigidly secured to the housings and extending across over the saddle being located forward of the strut in the general common plane of all the planer tools, a rearward extension of the saddle serving to secure it to the strut: 32, a vertical slide mounted in saddle 31: 33, a hori- .zontally sliding tool-rest mounted on the Fig.3, the feed for upper ortion of vertical'slide 32: 34, a tool carrie by tool-rest 33 and projecting inwardly: 35, a vertical feed-screw for slide 33: 36, a handle shaft for turning screw 35: 37, the feed screw for tool-rest 33: 38, the handle shaft for turning this screw: and 39, a vertical slide-bearing between the rear ortion of vertical slide 32 and a portion of s ide 31 projecting directly forward from the strut, the contact surfaces of this slide bearing being at right angles to the direction of planing motion. 1

The general member projecting forward from the strut and carrying vertical slide 32 and its tool accessories forms an appliance somewhat after the nature of a slotting machine and is capable of working within the confined space previously referred to and planing the surfaces 6 and .7 indicated in planing surface 6 being derived from screw 37, and the feed for planing surface 7 being derived from screw 35. The structure which has been likened to a slotting machine might in' many cases be substantial enough for its work without other sup ort than that derived from the strut, but y providing its forward end with the saddle 31 engaging the rail on the face of the super-table the structure may be given ample stability regardless of the reach of the arm extending forward from the strut.

Looking at Fig. 3 of the drawing it will be apprehended that two of these cylinders co-acting as a pair on a locomotive would represent rights and lefts while the laner devices specifically illustrated are a apted for planing but one of the cylinders when they are considered as ri hts and lefts. But it is to be understood, first, that if it were necessary the planer shown as being equipped with the special planing devices upon one side only could be similarly equipped upon the opposite side, thus adapting it for right and left-hand work and, second, that the two cylinders of a pair, while ossibly made from different patterns, and constituting rightand left-hand members of a pair, may be treated as identical upon the laner by reversing one of the cylinders en wise and securing it to the planer in such reversed position.

In the drawing the movement of the radius-bar is illustrated as being derived from link connecting the last-mentioned a side-head sliding vertically on the housing, but it is manifest that the link connected with the radius-bar may derive its motion from any other device capable of giving endwise motion to the link such, for instance, as one of the saddles on the rail.

In the exemplifying embodiment of my invention the arm which supports tool 34 is illustrated as being founded on a strut having its ends secured to the planer-housings, but it is manifest that this strut may find its equivalent in any other suitable firm support for the rear end of the arm.
